Abstract
Fracture split connecting rod has developed for commercial diesel engines for its advantage in improve engine performance and reduce production costs. Engine up rating is done as the need is arise for more energy output from the same volume of the cylinder. This connecting rod is made of high carbon micro-alloyed steel with controlled cooling and the blank is forged in one die mold and later fracture splitted. This connecting rod needs no additional rod and Cap contact face milling which means a substantial savings in Machining cost. A better contact between rod and cap improves stiffness and compatibility with crank train moving parts. This connecting rod is designed for Brake Main Effective Pressure (BMEP) 2.0 MPa and peak firing pressure of 180 bar. Analysis and optimization are done for tensile and compressive strength in both max. torque and over speed condition. After completion of connecting rod fatigue test, engine dyno durability and accelerated durability test on 25T Truck vehicles, no connecting rod failures are reported.
